Answer:

28cm

Step-by-step explanation:

Hi!

Let's find the area of the rectangle (we can form) and then tack on the area of the triangles.

We have 4 * 3 = 12. So the first area is 12.

Now, the triangles. We see that they will have base 4, and leg 2.

Using the Pythagorean Theorem:

4² + 2² = 20. √20 = 2√5. That won't really matter however, because we will multiply 4 by 2 to find the area.

4 * 2 = 8

The same will happen on the other side:

4 * 2 = 8 (note that we could've created a rectangle out of the triangles, but that would give us 16 too.)

8 + 8 = 16.

16 + 12 = 28

Thus, the area is 28 cm.

Hope this helps!

Answer:

Step-by-step explanation:

Right off the bat, you will know the lowest number is 52 and the highest number is 65, therefore there will act as the guides for your box and whisker plot. This eliminates answers B and C because they are not accurate to that.

Next, we find the median of the set of numbers by crossing out (writing it down, or imagining doing so) the numbers on either end consecutively to until you reach the center number, ours being 58. This eliminates answer A.

This leads us to belive answer D is the correct box and whisker plot.

castortr0y [4]

Answer:

The product is approximately 5400.

Step-by-step explanation:

9 1/16 rounded to the nearest whole number is 9.

645 3/5 rounded to the nearest hundred is 600.

Multiplying these values gives a product of 9·600 = 5400.

The product is approximately 5400.

Answer:

Mean: 1.5

Standard Deviation: 0.9

Step-by-step explanation:

2/3 of the pages have diagrams, and N is the number of pages Harlee reads to reach a page with a diagram. In order to find the mean, divide 1/(2/3) to get 1.5 as your mean, and then divide sqrt(1-(2/3))/2/3 to get .8660, which rounds to .9.
